Description

Technical Field

[0001] The invention relates to the technical field of casting processing equipment, in particular to a casting riser cutting machine. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. Castings obtained by casting are called castings. There is a channel between the casting cavity and the outside world, which we call a riser. This riser allows the metal liquid to enter the casting cavity. After the metal liquid cools, it forms a casting. At this time, the riser section on the casting needs to be cut off, so a riser cutting machine is needed.

[0003] With the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly increasing, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. The development of CNC cutting machines must adapt to the requirements of the development of modern mechanical processing industry. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water cutting machines, wire cutting machines, etc. Laser cutting machines have the fastest efficiency, the highest cutting accuracy, and generally small cutting thickness. Plasma cutting machines also have fast cutting speeds, and the cutting surface has a certain slope. Flame cutting machines are aimed at thicker carbon steel materials.

Before the shape positioning component 3 moves to one side, the casting pallet 4 needs to be moved backward. At this time, the fingertip 43 needs to be pointed to the data on the length scale bar 42 for recording. When the shape positioning component 3 is moved into place, the casting pallet 4 is reset so that the casting pallet 4 moves to the recorded data.

[0043] In a preferred embodiment, the bottom of the movable bracket 501 is fixedly equipped with a fitting movable bracket 508, and the inner wall of the bottom of the fitting movable bracket 508 is slidably connected with a fitting slide rail 509. The fitting movable bracket 508 moves on the fitting slide rail 509, so that the fitting movable bracket 508 drives the movable bracket 501 to move when it moves, so that the movable bracket 501 can move toward the direction of the casting.

[0044] In a preferred embodiment, the fitting movable frame 508 is connected to the fitting slide rail 509 via a fitting spring 514. Two fitting springs 514 are provided. By utilizing the setting of the fitting springs 514, the fitting springs 514 can pull the fitting movable frame 508 toward the casting, so that the molding contact strip 502 can fit the molding on the strip block 302.

[0045] In a preferred embodiment, a transverse moving frame 510 is fixedly installed at the bottom of the fitting moving frame 508, and a transverse slide rail 511 is slidably connected to the inner wall of the bottom of the transverse moving frame 510. The transverse moving frame 510 moves on the transverse slide rail 511, so that the transverse moving frame 510 can drive the moving bracket 501 to move laterally, and the electrode wire 506 is driven to move by the transverse movement of the moving bracket 501, and the riser is cut by the electrode wire 506.

[0046] In a preferred embodiment, the inner wall of the bottom of the transverse moving frame 510 is threadedly connected to a moving screw rod 512, and the outer edge of the moving screw rod 512 is fixedly sleeved on the power output shaft of the moving servo motor 513. The moving screw rod 512 is driven to rotate by the movement of the moving servo motor 513, so that the moving screw rod 512 drives the transverse moving frame 510 to move, so that the moving bracket 501 can be moved.

[0047] Working principle: when in use, move the modeling positioning component 3 to the middle position of the casting support plate 4, and then place the casting on the casting support plate 4, and then fix it. At this time, the riser on the casting corresponds to the modeling positioning component 3, and then move the strip 302 on the modeling positioning component 3 toward the casting. At this time, the heads of multiple strips 302 are in contact with the casting, and the tails of multiple strips 302 are the same shape as the bottom of the riser of the casting. At this time, the wire rope 311 and the rubber sleeve 312 at the tail of the strip 302 are the same shape as the bottom of the riser of the casting. By tightening the fixing nut 306, multiple strips 302 are fixed at this time, and then the casting support plate 4 is moved outward. At this time, remember that the fingertip 43 points to the data on the length ruler 42, and then move the modeling positioning component 3 to the right. After the movement is completed, reset the casting support plate 4 to the recorded position, and then pull the wire cutting component 5 backward to make the wire cutting The molding contact strip 502 on the component 5 contacts the rubber sleeve 312 at the tail of the strip block 302. At this time, the elastic force of the molding spring 514 moves the molding movable frame 508 and the movable bracket 501 toward the casting. At this time, the transverse slide rail 511, the movable screw rod 512 and the movable servo motor 513 slide in the warehouse box 2. At the same time, the movable servo motor 513 drives the movable screw rod 512 to rotate. The rotation of the movable screw rod 512 drives the transverse movable frame 510, the molding movable frame 508 and the movable bracket 501 to slide on the transverse slide rail 511. At this time, the electrode wire 506 on the movable bracket 501 is in an energized state. At this time, the temperature of the electrode wire 506 is higher than the melting point of the riser. The riser is cut by the movement of the electrode wire 506. When copy cutting, the processed parts are placed on the casting support plate 4, and then they are finalized by the molding positioning component 3, and then the steps of cutting the riser are the same.
